' N. 3., a corporation of New Jy Application January at, 19st, Serial No. name M Claims. (Ci. nit-rat) This invention relates to the art of manifolding, and more particularly,-to the making of manifold copies in a typewriting machine and'maintaining the copies, which are. usually printed in registration so that matter written on the top or original copy will be reproduced in thesame place on the undericopies.

Heretoi'ore it was proposed to secure together in registration a plurality of record strips interleaved with a plurality of carbon strips, both in continuous form; so that the manifolding pile thus formed could be fed with the several strips traveling substantially as one. Y The product thus formed is useful and has many advantages in many applications. In feeding such strips around a cylindrical platenof a typewriter by friction, however, there is an inherent differential movement or creep between the several strips of the pile and resulting from each strip on the platen adding to the effective diameter thereof. The diihculty is well known by those skilled in the art, and the phenomena is known as creeping.

The diiilculty has been avoided by positively feeding the strips around the platen rather than frictionally, but this requires the provision of sprocket holes in the pile of paper and sprocketsv and the platen, and preferably close to the line of 5 engagement of. the pressure disks with the paper or pin-bearing bodies traveling with the platen to engage the sprocket holes.

I have found that when apile of strips, which are secured together 'at intervals, as, for instance, by staples, is fed around the platen, there is a slight bunching or crinkling of the papers when the staple or other securing means is reached by thefeed mechanism, and that, sometimes, this hunch is pressed down and passes the feed mechanism, but more often, after a number of forms have been fed, the creep between the several strips is suflicient to cause the paper to tear away from the staple with the result that the several record strips fail to register with each. other.

According to the present invention, the very satisfactory and desirable fastened pile of maul-- folding strips may be used with the friction type feed, requiring no rows of marginal sprocket holes.

I This is accomplished by providing, in the pile of strips, physical alterations at predetermined intervals, and arranging the feedmechanism so that pressure rollers will enter the physical alterations periodically inthe feeding of the pile, and thereby relievingthe pile from feedin pressure and freeing e several strips for relative movement intqfr'g'istration as fixed and controlled by the strip-securing means. In this relative movement, the creep inherently accumulated in the pile during the frictional feeding of that portion of the strip in advance of the physical alterations is dissipated.

In the form of the invention herein disclosed, the physical alterations are usually in the form of operative notches located in the side margins of the pile, and the feeding means is in the form of annuli or disks in longitudinal alignment with the feed-arresting apertures, so that when the disks enter the aperturesthe strips are relieved of feeding pressure as aforesaid, and the slight bunch in advance of the securing means may become smoothed out.

These notches not only cause the feeding pressure on the strips .to be relieved, but, also, interrupt the feeding operation, so that, in ajew idle operations of the platen, the paper strips may and will be jogged into alignment with each other as controlled by the securing means, usually staples preferably secured in substantial lateral alignment with the notches. To assure the possibility of rotating the platen without advancing the strip when the feeding disks are in the apertures of the strips, there is preferably provided between the lowermost one of the pile'of strips and platen, a dragbar or other device for retarding the free advancement of the paper strips.

According to the present invention, the usual paper table of any commercial typewriting machine is employed to cause the pile of strips to be introduced tov the platen and to generally conform to the curvature of the platen as the print-l ing point of the machine is reached, but the usual feed rollers are dispensed with or rendered inoperative, and the pressure roller of the present invention, which preferably engages the paper and the platen above the writing line, serves as the means for causing the pile of paper strips to travel with the platen. I

The feed-arresting pressure-relieving notches in the pile of the present invention are usually spaced along the pile at form-length intervals, andare preferably located coextensive with transverse lines of weakness along which one form or sheet-length'of the pile may be severed from the remaining.

It will be seen that the presentinvention does not contemp ate the elimination of creep during the feeding of each form-length, but, rather, dissipates the creep at each form-length and avoids the accumulation of] creep from form-length to form-length which would cause the several strips to shift out of registration with each other. The amount of creep existing for any one form-length is not suflicient to be commercially unacceptable, but any creep extending for several form-lengths would be unacceptable for practical purposes.

The pile of papers which has come to rest for realignment to dissipate the creep may be repreferably located somewhere between the securing means and one or both of the lateral margins of the pile.

In the broader aspects of the invention, the feed-arresting apertures may be contained within the body of the strips, or they may be at the top of a form or near the bottom, and even when contained in the body of the form, they may be coincident with the line of weakness between forms.

It is preferable, however, to have the notches in the side margins, for then the pressure rollers will engage the extreme side margins of the pile,

and these margins on the carbon strips may be either removed or left uncarbonized, thereby avoiding the production of marks on the under copies produced by the overlying carbon strips being pressed thereagainst by the rollers. I

Attention is called? to a companion application filed concurrently herewith in which the manifolding piles described and illustrated herein are described and claimed per se, for, while the manifolding piles illustrated herein cooperate in a special way with the typewriter and parts thereof, these manifolding piles are capable of use with mechanism quite different from the mechanism herein disclosed.

As shown in the accompanying drawings, the invention is applied to a front-strike typewriting machine havnig a cylindrical platen l0 mounted in a carriage frame II, which, usually, is provided with feed rollers l2 adapted to press worksheets or strips against the platen to cause the same to advance therewith as the platen is r0- tated line-by-line by line-spacing mechanism including a ratchet wheel l3 mounted on a shaft I4 carrying the platen and itself rotatably mounted in the carriage frame I I.

Paper sheets or strips are guided to the platen by a paper table l5, and an apron l6 causes the paper to follow the curvature of the platen and a lie close thereto at the line of writing I! where Fig. 6 is a similar plan view showing/a modiapertures being in the heads of the forms.

typebars I8 strike upon the platen.

The feed rollers I 2 may be released by the operation of a lever I9 and linkage 20 so as to be spaced from the platen and to likewise drop the paper apron for the usual introduction of the paper-to the platen.

The machine has a bail, including side arms 2!, which usually supports between th'em a rod which carries a pair of auxiliary pressure rollers engaging the work in advance of the line of writing. The arms 2| are usually yieldingly mounted, but, in adapting the machine to the/"present invention, the arms 2| are'locked down by latches 22 pivoted at 23 on the ca riage. [The rod and auxiliary rollers supplied with the machine are also discarded. I

As stated above, the present invention provides for continuously making manifolding recordswithout resorting to ;the use of feeding pins or the like, or the provision of pin-engaging apertures in the recoi strips and yet maintain satisfactory registr tion between the printed matter on the several' record strips.

This is accomplished by such organization of and cooperation between the manifolding pile, including the record and transfer strips and the feeding parts of the typewriter that, while the pile is fed frictionally line-by-line past the line of writing, the feeding pressure on the pile of strips is released periodically to allow the creep accumulated between the several strips to'be dissipated by the natural. tendency of the strips to realign under the control of means securing all of the strips together in registration. The strips are assisted in becoming realigned by the jogging of the machine 'incident'to the travel of the carriage. and the idle rotation of the platen while the pile of strips is relieved of feeding pressure.

As illustrated in the accompanying drawings,

the manifolding pile is made up of a plurality of record strips 24, each continuous, and provided with a succession of printed forms 25. In

terleaved with the record strips 24 are a plural ity of continuous carbon sheets 26.- The record strips 24, and preferably the carbon strips 26 also, may be provided with transverse lines of other strips in substantially the same places by staples 28 in the form illustrated, but other forms ofsecuring meansknown to the art or found suitable may be employed. The staples Rare preferably located directly on-the lines of weakness 21. in the record strips so that when a completed set of forms is'torn off, the'staple is no longer operative to hold the resulting record sheets together, and theresulting carbon sheets may be separated therefrom. To facilitate this, the lines' of separation in til strips may deviate, in the now well known manner, from thoseof the record strips so that tabs 29. are formed on the carbon sheets at one end of the pile of sheets and notches are formed in the carbon sheets at the. other end of the pile. By grasping the tabs 29 of the carbon sheets with, the fingers of one hand and the record sheets over the notches 30 at the other end of the pile and drawing the hands apart, the

e carbon carbon sheets and the record sheets are stripped "from each other. By placing the staple 28 in the portion of, the sheets adjacent the tabs 29, 'the' entire group of carbon sheets is .held togeher as a unit in the stripping operation, and the staple is prevented from falling into the typewriting machine where it might cause trouble. With the strips 24 and 26 stapled or otherwise fastened together at intervals along-the pile, as

the pile is fed frictionally the inherent tendency to creep causes the, strips to advance at differment which has occurred between the strips durcut rates of speed, depending upon their nearness to the platen.

The excess of paper incidental to each form fed must be-bunched in advance of the staple and pass by the feeding means, otherwise it ac- .cu'mulates from form to formuntil the excess becomes so great that the paper tears loose from the staple and practical registration is destroyed. Reliance cannot be placed upon the bunch of excesspaper goingthrough the feed mechanism without tearing away from the staple, and hence it is customaryfor operators using stapled paper j to remove the paper from the machine from time to time and cause it toregister.

To obviate the necessity ,of doing this and to positively avoid creep accumulating from form to form, the manifolding pile of the present inventi-on is provided 'with physical alterations, preferably apertures, and the feeding means comprises relatively narrow disks or annuli adapted to enter the apertures or .other physical alterations and relieve the pile of strips of feeding pressure so that the accumulated during the feeding of one form-length in advance of the staple may be dissipated.

In the form of the invention shown in Figs. 1

to 6, the physical alterations are in the form of notches 3i provided in pairs along the lateral margins ofthevpile. when the carbon strips 26 are full width as shown in Fig. 5, they, too, are provided with otches 3|, but, when the carbon strips are narr w as shown in Fig. 6, they need not be provided with the notches. If the wer bon strips 26 are wider than shown in Fig. 6 but not as wide as shown in Fig. 5, they will be notched as much as needed to conform with the notches in the edges of the record strips 24.

In practicing the present invention, the usual feed rollers I2 are released by the operation of the lever i9 so that the pile of strips is substantially free of feeding engagement with the platen below the line of writing H.

against the platen and the pile of papers carried thereby. To keep the. bail arms2l from being raised as a result of the pressure of the rollers .32 against the platen, they are provided with a pin 38 engaging a notch in the locking arms 22 referred to above.

After theleadlng edge-of the manifolding pile is placed m, the paper table l5 and is introduced around the platen and placed under the pressure disks 32, the rotary movement of the platen will cause the pileof strips to advance line-byline with .the platen until the notches 3| reach the bight of the rollers 32, at which time the ro lers enter the notches and relieve! the pile of strips 24 from feeding pressure. -When the strips 24 and 26 are thus relieved, they may shift relatively to dissipate any creep or relative moveing the feeding of one-form length and assumed proper registration as controlledby the 'securing .means such as the staple 28.

Preferably, the feed-arresting notches 3| are in lateral alignment with the staples so that the strips are relieved from feeding pressure just about the time when the maximum amount of creep exists, thereby avoiding carrying over to the .next form any of the creep, even though, that amount of creep is not sufficient to cause. the staple to tear through the paper.

Preferably, also, the notches II are coincident with the lines of weakness 2! which preferably carry the staples 28, for the hatches facilitate the starting of the tearing operation when the written'form is to be torn-off along the lines of weakness, and, when the staple is located on the line of weakness, it-will be removed with the carbons of the written form being located in the.

tab 29.

. The resiliency of the paper is sufllcient in most cases to cause the bunchin advance of the staple to disappear immediately upon the release of the feeding pressure. However, the idle operation of the machine, that is to say, the rotation of:

the'platen, and the return of the carriagewhile the feeding pressure is relieved, also tends to jog the several strips into registration. Besides this, the engagement of the feeding disks with the leading edges of the apertures, that is to say, the bottom edge of the written form in the construction shown in Figs. 1 to 6, also tends to move the strips into registration and particularly into alignment with the line of' writing of the typewriting machine.

To insure against the platen inadvertently advancing the pile of strips while the disks 32 are located in the notches 3| or other apertures performing the same function, the present invention provides a drag plate 39 adapted to be located between the platen and the pile of strips and between the writing line I1 and the bight of the disks 32. The plate 39 sufficiently separates the pile of strips from the platen so that rotation of the platen while the disks are in the apertures does not advance the strips. The form and position of the drag plate shown in the accompanying drawings has been found satisfactory in use, but it should be understood that any suitable separating and retarding device may be employed.

In the form of the invention herein disclosed, the plate 39 has vertical ears 40 secured to arms 4! carried on the pins 38 in the bail arms 2|.

tatably mounted on the rod 33 which supports the pressure rollers and has diametrically oppo-' site cutaway portions 49, one of which normally faces the paper strips and the platen. The roller 48 has a sleeve portion 50 having two flats parallel with the cutaway portions 49, and these are engaged by a leaf spring 53 mounted on a collar 54 carried by the rod 33 so that a cutaway portion 49 is normally located in the position shown in Fig. 15. The sprin 53 may be covered and protected by a housing '55. The starting roller 48 also has a pair of pins 56. These are so located as to be engaged by a lug 51 on a key 58 pivotally mounted at 59 on a bracket 60 secured to the rod 33 and having a spring 6| adapted to hold the key in the position shown in Fig. 15. When it is desired to start the strips so that they will advance with the platen, the key 58 is depressed causing the lug 51 to engage one of the pins 56 and rotate the starting roller until the periphery thereof just engages the paper as shown in Fig. 16. With the parts in this position, the platen is line-spaced, and this causes the pile of strips to be pressed against the platen by a starting roller 48. When this has occurred,

the key 58 is released, removing the lug 51 to The separating and retarding plate 39 may be I provided with lateral guides 42, which, in cooperation with lateral guides 42a on the paper table l5, assist in keeping the pile in proper position on the platen with the notches 3| longitudinally aligned with the feeding disks 32.

So long as the feeding pressure of the disks 32 is not applied to the pile of strips, the platen may be operated idly without advancing the strips. To cause the strips to again advance, the pressure may be applied to the strips so that they frictionally engage the platen in any suitable way.. This may be accomplished by temporarily returning the feed rollers i2 to operative position, or it maybe accomplished by the operator pressing her finger against the pile of papers on the platen while line-spacing the same.

However, it is preferable to have a mechanical device to perform this function, and, as shown in Figs. 2, 3 and 4, the present invention provides auxiliary pressure rollers 43 carried by a frame 44 urged to inoperative. position by a spring 45 and provided with a finger-piece 46 whereby the rollers 43 may be swung down into engagement with the pile of papers on the platen at a point remote from the apertured portions of the strips. With the frame 44 held down as shown in Fig. 3, line-spacing movement of the platen causes the paper strips to advance until the pressure disks 32 move out of the notches 3i and again engage the lateral margins of the paper strips.

The starting rollers 43 are so placed on the frame as to produce a downward pressure on the paper without themselves tending to advance the paper, for, if this occurred, the top strip, which is directly engaged by the starting rollers, might be shifted out of registration.

When the starting mechanism is located mid-' way between the pressure rollers 32, that is, at

the center of the paper strips, it might be interfer-ed with by the staple 28, and hence, in the form shown, there are two starting rollers 43 connected together by a sleeve 41 separated a sufficient distance to straddle the staple.

In Figs. 15, 16, 1'7 and 18, a different form of starting mechanism is shown. In this form of the; invention, the starting roller 48, preferably ofj 'rubber or other soft material, is rothe position shown in Fig, 15 so that the other pin 56 may be moved to the position shown in Fig. 15 as the starting is rotated one half revolution, which movement is completed by the spring 53 which holds the starting roller in this position until the starting operation is to be manually initiated and repeated.

The rod 33 is held in th arms 34 against turning, and, therefore, the parts of the starting mechanism which are not intended to rotate may be secured in fixed position on the rod 33.

The feeding disks 32.are adjustable longitudinally of the rod 33 so as to bring them into proper alignment with the feed-arresting apertures in the paper strips. They may conveniently be held in adjusted position by collars 62.

When the feeding disks engage the lateral margins of the record strips 24, any tendency for the feeding disks to cause marks to be made on the under copies through the carbon may be avoided by providing on the full-width carbon strip 26 a clean marginal band 63, as shown in Fig. 5, but, if this is not desirable, the carbon strip may be made narrow so as not to extend to the line. of feed in the record strips, as shown in Fig. 6.

In the broader aspects of this invention, the feed-arresting form registering apertures in the strips need not be in the lateral margins, but, as shown in Figs, 7 to 13, inclusive, they may be located inwardly of the margins of the strips.

In the form of the invention illustrated in Fig. 7, there are employed circular apertures or holes 64 located a substantial distance from the lateral margins of the pile. In Fig. 9, the apertures 64 are located in the head of the form so that the staple is in'advance of the apertures. This construction may be used advantageously where the bunching which results from the feeding of one form-length is not suflicient to tear the staple from the paper, for the creep will be dissipated when the feeding disks enter the apertures 64,

even though the staple has passed the line of .the form shown in Fig, 11 may under some conditions be preferable to the form shown in Fig. 9.

The feed-arresting apertures need not be round holes as in Figs. '7, 9 and 11, but may be of anyv desired shape.

or square, so that the feeding disks .or annuli 32 may enter the apertures and relieve the paper strips of feeding pressure Again, the marginal apertures need not be in the form of notches, as in Figs. 1 to 6, but may be located in the margins of the strips and be in the form of holes, such as the holes in Figs. 8, 10, 12 and 13, which do not intersect the lateral edges of the paper strips.

With the constructions shown in Figs. 8, 10, 12

w and 13, it is possible to have the feeding disks engage the paper without danger of marking the under copies, and yet the lateral edges of the paper strips are .continuous and may be more easily guided by usual lateral guides in For instance, they may a be oblong as shown in Figs. 8, 10, 12 and 13,

manufacturing the manifolding pile and in using 7 it in the ty'pewriter.

When the apertures are in the foot of the sive, or may be partially thereon like the notches 3| in Figs. 5 and 6, and they may be behind the.

lines of weakness 2! as in Fig. 12 or in advance as in Fig. 13.

Likewise, the notches in the lateral margins need not be in the lines of weakness as in Figs. 1 to 6-. Instead as shown in Fig. 14, the notches 3| may be removed more or less from thetear lines 21. t

Regardless ofthe locations'of the apertures, the feeding disks 12 are, as shown in Fig. 8, brought into longitudinal alignment with the apertures so that the feeding pressure is relieved when the apertures reach the line of feed.
